​ROM is composed of: ​

Correct option is C

The correct answer is (C) integrated circuits.

Explanation:

• ROM (Read-Only Memory) is made using integrated circuits that are specifically designed for storing data that cannot be easily modified or written over.

Incorrect Options:

• Semiconductors: While semiconductors are used in various components of ROM, the actual construction of ROM involves integrated circuits.
• Photoelectric cells: These are used in sensors, not for memory storage in ROM.
• Magnetic tapes: Magnetic tapes are used for data storage but are unrelated to ROM construction.

Information Booster:

• ROM is crucial for storing firmware and software instructions that remain intact even without power.
• Integrated circuits in ROM allow for compact and efficient data storage.
